Compatibility notice: This feature relies on a WordPress action hook that is not included in WP’s FSE menus. This only works with menus that use wp_nav_menu_item_custom_fields.
You can set display options for individual menu items to identify whether a menu item displays to a logged in user, logged out user, or all users.
If you are also using defined memberships, you can set which memberships a menu item may display to, in addition to logged-in/logged-out options.
Menu settings are available when editing individual menu items under Appearance > Menus. They do not currently display when viewing menu items in the Customizer.
